This PR updates existing backends to implement the `IRenameEnabledBackend` interface, allowing for more efficient file renaming operations. The implementation varies by backend, with some using native rename operations and others falling back to copy-and-delete patterns.
This PR adds a dynamic property so a backend can signal if it supports streaming, based on the settings.
This is currently used for the File backend, so that toggling `--use-move-for-put` will disable streaming on the backend instead of relying on the `--disable-streaming-transfers` flag.
This PR removes the `OAuthContextSettings` class, and makes the `--oauth-url` option available on each backend that uses it, so it can be configured as part of the destination.
To assemble everything related to configuring OAuth, the code was moved to the `AuthIdOptionsHelper`, such that the usage can be shared between implementations.
This PR also adds the option to set the default OAuth url from the environment variable `DUPLICATI_OAUTH_SERVICE`.
The server can then be set in the following locations (most important last):
- Environment variable
- Server-wide advanced settings
- Backup job advanced settings (or commandline)
- Destination url
This PR moves the check from the FTP backend into shared code, so all backends will now check for read/write permissions when using the "Test" button.
For situations where write permissions are not required (like restore or verify) there is a flag on the v2 API that indicates if the connection was established, so the UI can show a message suggesting that it is possible to proceed, if the current UI operation does not require write permissions.
This fixes#2473
This PR is the final change, where all backends are now purely implemented with async interfaces.
The code changes here replace the LIST call with an async version. This affect all backends (and then some) but the changes are mostly mechanical rewrites of the code.
In many places, the backeds were already prepared for async output, in other some glue was needed.
To reduce the scope of this change, some backends simply report a synchronous result as an async list.
- Add support for subfolders
- Implement robust file selection using fileID for Download/Delete operations instead of concatenation of path + filename
- Improved validation for folder existence during backend connectivity tests supporting subfolders.
This issue does not affect the pCloud backend per se and its functioning as expected.
The issue is related to a symptom the BackendTester revealed as discussed here:
https://github.com/duplicati/duplicati/pull/5709
It turns out the backends should assume the caller has set the input stream at the correct position and take it from there.
Therefore the fix is simply to remove the .Position = 0; which was well intended as a way to make sure the stream was at the beginning, but thats not the pattern to follow when integrating backends.
A future blog post/tutorial on new backend integrations will mention these premises.
